Brief Description

Autoit.KY is a worm that spreads by copying itself, without infecting other files.

It affects productivity, preventing tasks from being carried out:

In the affected computer:
it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.

In the local network:
it generates a large amount of network activity and consumes bandwidth.

It uses stealth techniques to avoid being detected by the user:

It uses techniques included in its code to hide itself while it is active.

It deletes the original file from which it was run once it is installed on the computer.

It modifies system permissions in order to hide itself.

Autoit.KY uses the following propagation or distribution methods:

Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.

Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
